“…Figure 3 shows that the autocorrelation coefficients of daily discharges reach a value of 0.2 in 63 days and a null value in 114 days. This can be explained by a strong memory effect of the aquifer (Mangin, 1984;Larocque et al, 1998) and the predominance of baseflow component (Padilla et al, 1994;Pulido-Bosch et al, 1995, 1999Cerôn et al, 1999). Figure 4 shows autocorrelation coefficients of monthly discharges of the Gradole Spring and monthly precipitation that fell on the catchment in the period from January 1987 to December 1998.…”

The problems and present methods for the calculation of monthly and annual effective infiltration coefficients in Dinaric karst catchments which cover areas smaller than 200 km 2 are discussed. An example is given of the catchment of the Gradole karst spring, which covers 114 km 2 . The climate on the catchment is North Mediterranean, with average annual rainfall of 986 mm, average air temperature of 11.4°C, and average discharge from the Gradole Spring of 1.98 m 3 s" 1. All the data refer to a period from 1987 to 1998. An auto-correlation analysis is carried out of daily and monthly discharges from the spring and monthly rainfall on the catchment. Special attention has been given to determination of monthly effective infiltration coefficients. It was found that the time-scale effect makes it infeasible to use the equation for effective infiltration coefficient, because it gives values greater than 1 in 25% of cases, which is theoretically impossible. Therefore, two different procedures for calculation of monthly effective infiltration coefficients are given, out of which one uses the master depletion curve. This procedure gives acceptable and physically well-established values of mean long-term monthly effective infiltration coefficients. Obtained values can be used for regional analyses as well as for water resources management in karst regions. There was also a strong relationship between mean monthly air temperatures of the catchment and mean monthly effective infiltration coefficients. It is found that rainfall distribution during the year significantly influences the annual effective infiltration coefficients, which for the Gradole catchment ranges between 0.356 and 0.763 with the mean value of 0.57.

“…That is why several regimes are considered in the discharge process. Padilla et al (1994) suggested that the discharge in karstic systems is represented by two components: one linear, described by the Maillet formula associated with the recession of the saturated zone; and the other, non-linear, referred by a homographic formula related to the non-saturated zone. Malik (2015) implemented an iterative solution of several exponential and linear relationships for the hydrograph separation.…”

Abstract:The identification of the moment when direct flow ends and baseflow begins is one of the biggest challenges of hydrological cycle modeling. The objectives of this research were: to characterize the recession curves (RC) and to separate the components of the hydrograph in a compact model. The RC were extracted from time series in three subwatersheds in Mexico. An expo-linear model was adapted and fitted to the master recession curves to find the transition point of the hydrograph and separate the baseflow. The model discriminated the RC in two decreasing ratios: one linear associated to the direct flow, and one exponential linked to the baseflow. The transition point between these two flows was obtained analytically by equaling both ratios. The derivation of a model parameter allowed to find the maximum points in the hydrometric time series, which were the criterion to separate the baseflow. The application of this model is recommended in the analysis of RC with different magnitudes from the flexibility and attachment to the fundaments of exhaustion of a reservoir.

We are very pleased with your decision regarding our manuscript. We addressed the very minor corrections pointed out by reviewer #2, as can be consulted in the DOC file Revision_Notes. The revised version of the manuscript is given in the DOC file Reviewer #1No corrections to be made. Reviewer #21)The abstract contains some formulas. I think it is better to delete them from the abstract.The formulas were deleted. 2)p.7, 155: Please check the calculation of percolation time of soil water to reach the bedrock. Based on the given K, it should be at least 3.75 days, i.e. >3.75 days.The sentence was corrected: where the text was "< 3,75 days" is now "at least 3,75 days". 3)p.8, 188-190: The sequence of sentences beginning with "Altogether." do not make sense. How does a model operating with a minimum amount of information affects the type of methods used in the model?The sentence was deleted (in fact, it was not an essential sentence). 4)Perhaps a better phrase can be used instead of the term "aquifer formation constant". It sounds like the hydraulic conductivity and porosity have something to do with the formation of the aquifer.Throughout the text (in 7 places), the term "formation constants", although used regularly in hydrologic texts to describe aquifer hydraulic parameters such as K and n e , was replaced by "hydraulic parameters". 5)p.19, 461-64: Here the authors mention that no spring flow discharge was information was available. However, it is not clear what was done to compensate for this. The authors should make it clear to the reader by rephrasing the sentence and using better wording, what was done exactly. Perhaps this issue can be clarified in the previous methods section of the manuscript.The way how we compensated for the lacking of spring flow discharges is explained in the section "Aquifer Formation Hydraulic Parameters and Travel Times of Spring Watersheds". However, in the section ("Aquifer Formation Hydraulic Parameters and Travel Times of Stream Watersheds") we now added the following sentence to make this more clear: "The hydraulic conductivities (K) and effective porosities (n e ) resulting from this characterization were then used as proxies of the K and n e values of the spring watersheds, as explained in the next section, which also describes how groundwater travel times were downscaled from the larger (stream) the smaller (spring) scales." The papers corresponding to the reference numbers are given in the legend of RESEARCH HIGHLIGHTS• develop a weathering model that incorporates rock structure in the rate equation• conceive a weathering model especially designed for fracture artesian springs•Create a model that integrates topography, hydrology, rock structure and weathering evaluation of morphologic parameters is subjective due to difficulties in conceiving the catchment 21 geometry.
